Cyber AB Certified CMMC Assessor (CCA) Exam 認定 CMMC-CCA 試験問題 (Q118-Q123):

質問 # 118
An OSC is preparing for a CMMC assessment. It has multiple information systems, some of which process CUI and others that do not. The OSC has identified a specific system that processes CUI and defined this as its system boundary. However, this system is connected to other systems within the OSC that are separately authorized and do not process CUI. As a Certified CMMC Assessor, which of the following best describes your approach to defining the CMMC Certification Boundary and Assessment Scope for the OSC?

A. The CMMC Certification Boundary and Assessment Scope should include all information systems within the organization, regardless of whether they process CUI or not.
B. The CMMC Certification Boundary should include the specific system that processes CUI. In contrast, the Assessment Scope should consist of all components of the information system that require authorization and excludes separately authorized systems to which the information system is connected.
C. The CMMC Certification Boundary should include the specific system that processes CUI, while the Assessment Scope should encompass all systems within the OSC.
D. The CMMC Certification Boundary and Assessment Scope should only include the specific system that processes CUI and exclude all other systems.

正解：B

解説：
Comprehensive and Detailed Explanation:
The CMMC Assessment Process (CAP) distinguishes the Certification Boundary (the CUI-processing system) from the Assessment Scope (all components needing authorization, excluding separately authorized connected systems). The scoping guide and glossary confirm that separately authorized systems are out of scope, aligning with Option D. Option A is too broad, Option B too narrow, and Option C reverses the definitions. D is correct.
Reference:
CMMC Assessment Process (CAP) v1.0, Section 2.1 (Certification Boundary), p. 8: "The Assessment Scope excludes separately authorized systems."

質問 # 119
During a CMMC assessment, the Lead Assessor requests evidence from the OSC to support their claim that several access control and authentication practices are inherited from their enterprise-level Identity and Access Management (IAM) system. The OSC claims that their parent company manages the IAM system.
Which of the following types of evidence would be the most appropriate for the OSC to demonstrate these inherited practices?

A. An attestation from a third-party auditor confirming that the parent company's IAM system is compliant with relevant security standards.
B. Verbal confirmation from the OSC's IT manager that the enterprise IAM system handles accesscontrol and authentication.
C. Documented policies, procedures, and system configurations from the enterprise IAM system, showing how the assessment objectives for the inherited practices are met.
D. A self-assessment report from the OSC stating that the enterprise IAM system meets the inherited practices.

正解：C

解説：
Comprehensive and Detailed in Depth Explanation:
The CAP requires detailed, documented evidence from the providing entity for inherited practices (Option A).
Options B, C, and D lack specificity or objectivity.
Extract from Official Document (CAP v1.0):
* Section 1.6.1 - Access and Verify Evidence (pg. 19):"Evidence from an enterprise for inherited practices must include documented policies, procedures, and configurations showing compliance." References:
CMMC Assessment Process (CAP) v1.0, Section 1.6.1.

質問 # 120
An OSC is a wholly owned subsidiary of a large conglomerate (parent organization). The OSC and the parent organization use ID badges (PKI cards) that contain a PKI certificate and a radio frequency identification (RFID) tag used for building and system access (including systems that process, transmit, or store CUI). The parent organization does not make any decisions on how the OSC runs its security program or other matters of significance. The large conglomerate operates a machine that is used to activate the badges for both itself and the OSC. This machine is isolated in a locked room and has no network connectivity to the OSC.
The badge activation system is:

A. In-scope because the parent organization acts as an External Service Provider to the OSC by providing PKI cards.
B. In-scope because the OSC is part of the large conglomerate and thus any CMMC requirements of the OSC are imputed onto the large conglomerate.
C. Out-of-scope because the badge activation machine is physically and logically isolated from the OSC and it is under the control of the parent organization.
D. Out-of-scope because the OSC is the one that assigns the appropriate access to a particular PKI card.

正解：C

解説：
According to CMMC Scoping Guidance, assets controlled by a parent organization are out-of-scope when they are physically and logically isolated from the OSC's environment and do not process, store, or transmit CUI within the OSC's boundary.
Extract from Scoping Guidance:
"Out-of-Scope assets are those that cannot process, store, or transmit CUI because they are physically or logically separated from CUI assets, or they are inherently unable to do so." Since the badge activation machine is completely isolated and managed by the parent organization, and it has no network connectivity to the OSC, it is out-of-scope.
Reference: CMMC Scoping Guidance, Level 2.

質問 # 121
A leading technology solutions provider that works with various government agencies and commercial clients has implemented a dedicated CUI enclave within its network infrastructure to ensure the secure handling of CUI. As a Certified CMMC Assessor, you are tasked with assessing the scope of the solutions provider's CMMC requirements. Which separation technique can the technology solutions provider use to isolate the network assets in its CUI enclave?

A. Segmentation
B. Physical separation
C. Logical isolation
D. Encryption

正解：C

解説：
Comprehensive and Detailed Explanation:
The CMMC Assessment Scope - Level 2 allows organizations to isolate CUI within an enclave using various techniques, with logical isolation being a recognized method. Logical isolation uses software and network configurations (e.g., firewalls, VLANs) to create separate segments within the same physical infrastructure, effectively isolating the CUI enclave without requiring physically distinct hardware (Option A) or broad network segmentation (Option B). Encryption (Option D) secures data but does not inherently isolate network assets. Logical isolation aligns with the scenario's use of a dedicated enclave within the existing infrastructure, as supported by NIST SP 800-171 and CMMC guidance.
Reference:
CMMC Assessment Scope - Level 2, Section 2.2 (Enclave Scoping), p. 4: "Logical isolation, such as VLANs or firewalls, can be used to isolate CUI enclaves."

質問 # 122
A contractor has retained you to assess compliance with CMMC practices as part of their triennial review.
During your assessment of the AU domain, you discovered that the contractor has recently installed new nodes and servers on their network infrastructure. To assess their implementation of AU.L2-3.3.7 - Authoritative Time Source, you trigger some events documented to meet AU.L2-3.3.1 - System Auditing across both the new and existing systems, generating audit logs. Upon examining these logs, you notice inconsistencies in the timestamps between newly installed and previously existing nodes. Further investigation reveals that while the contractor has implemented a central Network Time Protocol (NTP) server as the authoritative time source, the new systems are configured to automatically adjust and synchronize their clocks only when the time difference with the NTP server exceeds 30 seconds. Based on this scenario, how many points would you score theOSC's implementation of CMMC practice AU.L2-3.3.7 - Authoritative Time Source?

A. 0
B. 1
C. 2
D. 3

正解：A

解説：
Comprehensive and Detailed In-Depth Explanation:
AU.L2-3.3.7 requires organizations to "synchronize system clocks with an authoritative time source" to ensure consistent timestamps for audit records. The contractor has an NTP server, but the 30-second synchronization threshold on new systems leads to inconsistent timestamps, failing the practice's intent. Per the DoD Assessment Scoring Methodology, AU.L2-3.3.7 is a 1-point practice. If not fully met, it scores -1 (Not Met). The partial implementation (NTP server exists but not effectively applied) doesn't qualify as Met, so no positive points are awarded. The CMMC guide stresses uniformity in timestamps, which this configuration undermines.
Extract from Official CMMC Documentation:
* CMMC Assessment Guide Level 2 (v2.0), AU.L2-3.3.7: "Synchronize clocks to ensure uniformity of timestamps for audit records."
* DoD Scoring Methodology: "1-point practice: Met = +1, Not Met = -1."
